常见问题解答

问抑制剂是否需要灭菌？

答如果您使用 DMSO 配制：不建议灭菌，DMSO 本身具有极强的杀菌力，配制好的溶液就是无菌溶液。如果您确实担心的，可以放置 4℃ 冰箱过夜放置即可；依然有顾虑的话，需用有机系专用滤膜过滤。如果您使用水配制：可以用 0.22 μm 滤膜过滤灭菌。

问Tween-20 可以用 Tween-80 替代吗？

答不建议使用 Tween-20。相较于 Tween-20，Tween-80 的耐受性更好，Tween-80已被用作评估实验药物和毒物的行为影响的工具，且没有明显的副作用。参考文献：Castro CA， Hogan JB， Benson KA， Shehata CW， Landauer MR. Behavioral effects of vehicles: DMSO， ethanol， Tween-20， Tween-80， and emulphor-620. Pharmacol Biochem Behav. 1995 Apr;50(4):521-6.

问加药后检测结果没有作用，是不是产品质量有问题？

答产品质量没有问题，都是经过两次严格质检的，HNMR确定产品结构，HPLC确定化合物纯度。同一个抑制剂由于实验材料（细胞、动物）的不同，IC50 和实验效果也是不一样的，不能照搬文献报道的方法，应该根据自己的实验设立浓度梯度，得到一个最适合的浓度。

问如何选择合适的溶剂？

答常用的溶剂包括DMSO、水、乙醇等。建议您根据抑制剂给出的溶解度参考，选择合适的溶剂。如果该抑制剂可以溶于DMSO，建议使用没有吸潮新开封的 DMSO，如果有潮气污染，很容易带来抑制剂降解或难溶的问题。如果该抑制剂可以溶于水，建议您根据实验类型选择无菌水、生理盐水、无菌 PBS 、培养基等作为溶剂。

问溶解度中写的“< 1 mg/mL refers to the slightly soluble or insoluble ”是什么意思？

答这句话指的是，如果溶解度 < 1 mg/mL，那我们就认为它是微溶或不溶的，这是针对写的“DMSO：Insoluble”或“DMSO：slightly soluble”这类化合物的。

存储	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式	In general, Lyophilized powders are shipping with blue ice.
研究背景	Vascular endothelial growth factor (VEGF), also known as vascular permeability factor (VPF) and VEGF-A, is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. It is a member of the platelet-derived growth factor (PDGF)/vascular endothelial growth factor (VEGF) family and often exists as a disulfide-linked homodimer. VEGF-A protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, inhibiting apoptosis and tumor growth. VEGF-A protein is also a vasodilator that increases microvascular permeability, thus it was originally referred to as vascular permeability factor.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy
